Weight-Loss Peptides — Research Catalog Mexico

Selection of research peptides used in studies on fat loss, body composition and energy balance.

Research on fat loss with synthetic peptides has focused on compounds acting on the somatotropic axis, the ghrelin receptor and selective lipolysis. These peptides allow highly specific study of metabolic pathways in preclinical models.

Compounds such as AOD-9604, CJC-1295 and Ipamorelin are widely studied for their metabolic effects in vitro.

How do weight-loss peptides work?

Weight-loss peptides act on specific hormonal receptors that regulate appetite, fat metabolism and energy expenditure. GLP-1 agonists such as Semaglutide, Tirzepatide and Retatrutide activate the GLP-1R receptor in the brain and pancreas, reducing caloric intake and improving metabolic signaling. In phase 2 and 3 clinical trials, these compounds have shown body-weight reductions between 14.9% (Semaglutide, NEJM 2021) and 24.2% (Retatrutide, NEJM 2023). Somatotropic peptides such as Tesamorelin and Ipamorelin work differently: they stimulate growth-hormone secretion, which in turn drives lipolysis and reduces visceral abdominal fat.

Frequently asked questions about weight-loss peptides

+Which peptide burns the most fat?

According to clinical-trial data, Retatrutide showed the largest documented fat-mass reduction (−24.2% in phase 2, NEJM 2023), followed by Tirzepatide (−22.5%) and Semaglutide (−14.9%). These results are from pharmaceutical formulations in regulated trials. Peptide Life materials are for scientific research.

+What is the difference between Retatrutide and Semaglutide?

Semaglutide activates only the GLP-1 receptor. Retatrutide activates three receptors simultaneously: GLP-1, GIP and glucagon. This triple activation is the hypothesis behind its larger documented weight reduction in phase 2.

+Are weight-loss peptides safe?

Peptide Life peptides are Research Use Only (RUO) materials intended exclusively for in vitro scientific research. They are not medicines and must not be administered to people without medical and regulatory supervision. For obesity treatment, consult a physician.

+How much does Retatrutide cost in Mexico?

The 10 mg Retatrutide vial is priced at $2,070 MXN with VAT included, nationwide shipping and per-batch verifiable COA.

+Do you ship peptides throughout Mexico?

Yes. We ship to all of Mexico. Mexico City, Guadalajara and Monterrey receive within 24–48 business hours. Other destinations in 48–96 hours depending on courier coverage.
